I have turned the four-way buttons off. I agree with Greg that there should be a firmware update that addresses what I consider to be a problem - others may not agree that it's a problem at all.

In any case, I am one who likes to use a central focus point, half press the shutter to keep focus and exposure, and recompose before pressing the shutter all the way. Randy's instructions were very clear and I did this in less than a minute.
